PADLOCK.

SPECIFICATION forming part of Letters Patent No. 481,458, dated August 23, 1892.

Serial No. l30,855. (No model.)

To all whom it may concern.'

Beit known that I, NICHOLAS JACOB ZELL, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Padlocks; and I do hereby declare that the following is a full,

clear, and exact description of the same, refer-A aected by the rain or snow and still of few parts, and those cheap of manufacture, and when assembled so held as to prevent separation thereof.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof Will be specifically dein ed by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figures 1, 2, and 3 show the parts constituting my improved lock and the key dissembled, but in their relative positions, Fig. 1 showing the inner part in perspective with the hasp broken oft' and in section, Fig. 2

showing the outer part or barrel in longitudinal section, and Fig. 3 the key. Fig. 4 is a side elevation of the lock complete, with a portion broken away and parts in section, the view being at right angles to Fig. 1. Fig. 5 is an end view of the bottom cap or keeper. Fig. G is a cross-section on the line 6 6 of Figs. 1 and 2, with the parts assembled, but before they have been given the partial rotary movement hereinafter described. Fig. 7 is a crosssection on the line 7 7 of Figs. 1 and 2 with or barrel or casing of the lock. It is formed near one end with an annular internal shoulder d, against which the bottom cap or keeper A ts, as seen in Fig. 2, which keeperis held in place in any suitable manner. It is formed with a keyhole d', as seen in Figs. 2 and for the reception of the key B, which, as seen in Fig. 3, has two iins h, separated by a space b', as is also shown in said Fig. 3. The other end of this barrel is formed with an annular groove c2, as seen in Fig. 2, for the reception of an annular flange on the inner portion, soon to be described. The barrel is formed at a point substantially midway of its length with an olfset or shoulder c3, making one part larger in diameter than the other, as seen best in Fig. 2, and the upper or larger portion is formed with diametrieallyopposite longitudinal grooves d4, which extendfrom the upper end to the said shoulder a3 and then extend horizontally in opposite directions, as shown, forming, practically, bayonet-slots, and the horizontal portions of the slots, as seen in Figs. 2 and 6, are lettered c5. This constitutes the barrel, which may be of any suitable material, and the exterior may be made as ornamental as may be desired. The lower or smaller'portion of the barrel is provided upon its interior with a curved recess c, as seen in Fig. 7, starting -with the inner wall of the barrel and terminating in a shoulder a7, as seen in said Fig. 7, and the object of which will soon be made apparent.'

O is the inner part of the lock. It is formed with a reduced portion C', which is bored, as seen at c, and I) is a iiat spring, which is arranged in an annular groove in the exterior of this reduced portion, and one end is designed to extend through a hole c therein and into the bore of the said reduced portion, as seen in Figs. 7 and S. O2 is a ferrule over this reduced portion, and this ferrule is provided with a slot c3, through which the bend d of the spring extends, as seen in Figs. l and 7. The adjacent portion 02X of the inner part is formed with longitudinal ribs O3, designed to enter the longitudinal slots a4 of the barrel and then to enter by a partial turn of the inner portion relatively to the barrel the horizontal portions d5, as will be hereinafter explained. A shoulder d2 is formed at the IOO junction of the portions (32X and C3 to fit against the shoulder as of the barrel,as will be readily understood.

The outer portion is formed with a cappiece E, which has the annular groove e and flange e', as seen best in Fig. 1, the ange to t in the annular groove on2 of the barrel and the groove permitting the cap-piece to come over the upper end of the barrel and forma close joint to prevent ingress of rain or snow. The cap-piece is further provided upon diametrically-opposite sides of its flange portion with the slots E', as seen in Figs. l and 4, for the recept-ion and engagement of the horizontal lugs or pintles f of the ring or hasp F, which are free to turn therein,as will be seen from Fig. 4.

The parts operate as follows: The inner portion C is inserted withinthe barrel with its lugs in the longitudinal grooves of the barrel and the pintles of the ring in the grooves E of the cap-piece. The part-s are pushed together until the said ribs come to the terminal of the longitudinal slots or grooves, and then one of the parts is given a partial turn when the ribs travel `in the horizontal grooves of the barrel, and as this movement takes place the bend of the spring D springs out of the slot in the ferrule and engages the shoulder of the recess a6, as will be understood from Fig. 7, in which the parts are shown in the position they assume just as they are about being turned. The parts are thus locked and the pintles f are held in their grooves and against the upper end of the barrel where they are free to turn, but cannot be withdrawn. To unlock the parts, the key is inserted in the key-hole of the bottom piece and engaged with the end of the spring within the bore c, and when the key is turned the bend of the spring is drawn in and away from the shoulder a7, when the parts may be turned in the opposite direction until the ribs C3 come coincident with the longitudinal grooves of the barrel, and the parts may be then drawn outward one from the other andthe ring disengaged.

In order to prevent entire Withdrawal of the inner part, I provide the stop-pins G, which are held in the barrel and engage some stops on the inner part-as, for instance, the ribs CS--the pins being placed in position after the parts are assembled.

Modifications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as new isl. The combination, with the barrel and the partially-rotatable portion within the same, of the spring carried by the inner part and partially surrounding the same and designed to engage a shonlderon the barrel to prevent withdrawal ot' the parts, and means for preventing rotation of said parts, as set forth.

2. The combination, with the barrel having interior longitudinal and horizontal grooves and recess with shoulder, of the inner partially-rotatable part with cap-piece and ribs, and the spring partially surrounding the same and having a portion protruding to engage said shoulder,as and for the purpose specified.

The combination, with the barrel having grooves and recess with shoulder, of the inner partially-rotatable part having ribs and a ferrule with horizontal slot, and a spring having a bend protruding through the slot to engage said shoulder and one end extended within the bore of the inner part, as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses. y

NICHOLAS JACOB ZELL.
